Introduction

This is my final portfolio for VIS 2128, and displays a few of the maps I’ve made for the previous assignments.

Before this class, I had never worked with any sort of computer coding, much less any code used to create detailed and analytical maps. I am incredibly grateful for the skills I have gained, and hope these maps adequately show my progress throughout the module.

• Displaying multiple vector layers on the same map
• Calculating and displaying relationships among point and polygon layers based on distance
• Aggregating point data to a layer of polygons
• Calculating and displaying accessibility, based on travel time
• Converting between raster layers and vector layers
• Displaying raster data on a map
• Georeferencing a raster image
• Displaying data on an interactive map

Interactive Map

This interactive map demonstrates the following skills:

• Displaying data on an interactive map

Portland Map

This map demonstrates the following skills:

• Aggregating point data to a layer of polygons

Boston Isochrones

This map shows isochrones based on car travel times to the nearest police station. It demonstrates the following skills:

• Displaying multiple vector layers on the same map
• Calculating and displaying accessibility, based on travel time

#Historic Detroit Map This map shows accessibility based on a distance-decay function of the walking time to the nearest transit stop. It demonstrates the following skills:

• Displaying multiple vector layers on the same map
• Calculating and displaying accessibility, based on travel time
• Displaying raster data on a map
